The antigenic features of neuraminidases of several drift variants of influenza B virus were studied by enzyme immunoassay using antiserum to influenza B/USSR/100/83 virus neuraminidase isolated by pronase. Studies using immunosorption and competitive solid-phase enzyme immunoassay showed the presence in the antineuraminidase serum of at least two antibody subpopulations capable to inhibiting the activity of the enzyme and interacting with neuraminidase antigenic determinants: one detecting the antigenic determinant common for B/100/83 and B/Lee/40 viruses, and the other characterizing the antigenic determinant inherent in neuraminidase of B/100/83 virus and enzymes of drift variants isolated in 1970-1986 and lacking in the enzyme of B/Lee/40 virus.
